Cast Scratcher

so i have a cast after surgery and when its itchi i have this flat and round scratcher to give me reliefe.

print it with a 0.1 - 0.2 layer hight

infill: 20% that it is sturdy enough 

and smooth the top part with sandpaper or somting.

if you have a bigger cast than i, just scale it up

or use the 2nd file, attach a stick, rod or anything to it, with a 3x6mm screw or glue it in.
